Now I need to find out where Rich Snr's wife Margaret (abt 1845) and son David (abt 1861) were hiding when the 1881 census enumerator called. I have found a possible death for Maggie aged 32, so I don't know if she was still around then. I am also trying to confirm her maiden name. I came up with Morgans from somewhere but not sure it's right. A Mars bar to the first person with the answers!

Thanks
Chris
